熔制錠 的英文怎麼說
中文拼音 [róngzhìdìng]
熔制錠
英文
melted ingot-
Metallographic analysis indicated that sic particles dispersed separately and more uniformly in the parts than in the ingots and the stir techniques during remelting was decisive to the die - casting of the composite. the interface between sic particles and the alloy was clearer than that in ingots
對壓鑄件的金相檢驗表明，重熔攪拌工藝對復合材料壓鑄件的成功制備有重要意義； sic顆粒在壓鑄件中的分佈比在鑄錠中更為均勻，且呈單顆粒分佈， sic顆粒與基體結合處的界面也比鑄錠中更為清晰。In this paper, an ingot of niobium - niobium silicide based in - situ composites ( rmics ) was prepared by arc melting process, and nb - nb3si / nb5si3 in - situ composites with a uniformly orientated microstructure were produced in a high temperature gradient directional solidification apparatus named electron beam floating zone melting ( ebfzm ). the relationships between the processing parameters and the characteristics of the solidified microstructure have been investigated. the influence of the microstructure on the mechanical properties has been revealed and the rupture mechanism at room temperature has been discussed
本文採用真空電弧自耗熔煉法制備了鈮?硅基rmics材料的母合金錠，並採用電子束區熔（ ebfzm ）高溫度梯度定向凝固裝置制備了定向效果良好的nb - nb _ 3si nb _ 5si _ 3共晶自生復合材料，並對其定向凝固工藝參數和組織之間的對應規律、組織特性進行了研究，探討了凝固組織對室溫力學性能的影響及其斷裂機制。
